Hidden message within Trump campaign ad 

As they pan across the bridge of people standing on it, there is a blink of an eye, and moment that you see lettering in a message. I have slowed it down and got still framed pictures. It seems to be a safer message, as well as a message that has letters with pictures that are blurred in it. One appears to be a person bent over, holding their knees, and another is a dead face. A person believes it may say comply when it flashes.
